llVlACI-INE FOR BREAKING DOUGH.

Specification of Letters Patent No. 3,102, dated May 26, 1843.

To all whom, t may concern Be it known that I, LUKE SHAW, of Bath`county of Lincoln, State of Maine, have invented a new and usefulMachine for Breaking Dough Preparatory to Kneading the Same for Baking,of which the following is a full and exact description.

The nature of my invention, which I call the bakers friend, consists inapplying a crank, moved by hand or other power, affixed to the axle of acog wheel, which moves two other cog wheels, on the axle of each ofwhich is ailixed a crank, connected by a connecting rod to the outer endof a brake, the other end of which brake plays up and down in a mortise,secured by a pin or pivot, at the center of a circular platform,containing the dough, and revolving on trucks, by means of a bandpassing around it and over a pulley or axle, moved by another bandpassing o-ver the same, and also over the first axle. I

The machine is constructed by electing an upright frame, marked A, A,supported by four posts, marked B, B, B, B, in the drawing, rnilyconnected together by cross pieces or girts, C, C1, C2, placed atsuitable distances from each other to support the axles hereindescribed. On the middle of the girts or cross pieces marked C1, placedlittle more than one third of the distance from the top toward thebottom of the posts, is to be aiiixed on gudgeons, marked a, the axle,marked b, of a cogwheel, D, as large as the frame will permit, to bemoved by a crank, c, atlixed to the outer end of said axle. 0n the twocross pieces C2 place the axles of two other cog wheels, d, d, one oneach side` of the first, of the size proper to have the cog wheels meshin with those of the first axle. On the outerend of each of these twoaxles is to be affixed a crank, e, attached by a connecting rod, f, tothe outer end of a brake, marked Z, the other or inner end of whichplays vertically by a tenon secured in a mortise,rg, at the center of acircular dough platform, marked E, by a pin or pivot, so that the outerend of the brake may be alterare inserted into the` lower cross pieces,V

nearly level with the platform; the band passing iirst around rollersinserted into the upper and lower crosspieces, at equal distances oneach side of the axle, and at a distance from each other nearly equal tothe diameter of the platform, for the purpose of keeping the band inplace' on the axle or pulley; this last axle being moved by a bandpassing around it and also around the first axle. On the other end ofthe axlesl of the two upper cog wheels should be atlixed fly wheels, F,F, to regulate the motion. Instead of the band, cogs ori-the platformand axle intended to move it, may be substituted.

Another inode of operation is that of having a fixed semicircular orquadrant plat-k That l claim as my invention, and desirev to secure byLetters Patent, is-

The arrangement of t-lietable or platform,

and breaker, in combination with the cranks y i and cog gearing arrangedand operating in the manner herein described. y A
